It mainly focused on high-rise and all buildings of the city. For the two focus areas two different research methods were applied to answer the research question of the study accordingly. The first research method was an intensive building analysis based on 24 building parameters to identify the impact of geometry on the construction method and material of buildings, 40 high-rise buildings were deeply studied based on the parameters. The second research method was mainly based on a systematic questionier survey to identify the impact of geometry on the construction method and material of the entire buildings of the city. Besides the second method was used for realization of the level of the AEC industry in using advanced design and construction approaches and tools in deciding the architectural geometry and construction of all buildings of the city. The questionier survey was applied on 102 design and engineering firms. The main parts of buildings in which the research was focused on are the three major parts of a building, when combined they make a perfect geometrical solid, as a geometric solid is a combination of three surfaces to make a 3D volumetric object these are the base, vertical and overhead surfaces. Here in this thesis the base surface is the floor or slab of a building, the vertical surface is the façade of a building and the overhead top surface is the roof of a building. SPSS, STATA and advanced programing tools such as R-studio was used as a tool to make statistical analysis of data in a scientific manner. The former tools were used for descriptive statistics, correlations and multinomial regression model tests and the later tool was used to run complex multinomial logistic regression tests for datas which needs high performance statistical tools. Overall this thesis results a deeper understanding of the substantial role that geometry plays in determining construction practices and materials in the AEC industry. Through a comprehensive building analysis method, the research identified how geometric design choices influence the construction of high-rise buildings under method type one approach of the research. The findings provide a valuable knowledge in understanding the relation between building design and construction. Further, on method type two study approach, the thesis deeply explored the interplay of geometry with construction and identified the impact of computational design, digital fabrication and presence of specialized professionals on the geometry of our buildings to know how much our firm are applying such advanced design and construction approaches in the AEC industry or how much the geometry of the buildings is driven by advanced design and construction tools, approaches and professionals.
